→TLD Growth - Overview from 1983 to 2021
The [[Domain Name System|domain name system]] allows users to refer to websites and other Internet resources using names rather than the all-numeric IP addresses assigned to each computer on the Internet. Each domain name consists of a series of character strings separated by dots. The right-most string is the '''top-level domain (TLD)'''. Every TLD is managed by a single [[:Category:Registries|registry]].
